| Popis: | Background and Aims Intraoperative perforation is a major adverse event of endoscopic submucosal dissection (ESD). To avoid perforation, it is important for the endoscope to approach the portion to be resected carefully and to ensure that the knife can approach the submucosa at an angle parallel to the muscle layer. The multibending endoscope has 2 bends at its tip and may facilitate the ESD procedure. To the best of our knowledge, very few studies have reported the use of the multibending endoscope during gastric ESD. The aim of this study was, therefore, to introduce the usefulness of the multibending endoscope for gastric ESD. Methods We report 2 cases of early gastric cancer in which ESD was performed using a multibending endoscope. Results Unlike conventional single-bending endoscopes that have only 1 moveable part, the multibending endoscope allowed difficult areas to be approached more easily. Small adjustments could be made to the upward or downward angle of both the first and the second bending sections of the endoscope. This ensured that the knife would approach the submucosa at an angle parallel to the muscle layer. In patient 1, initially the conventional endoscope was used, but it became more difficult to approach the site, and paradoxic movement occurred. When the conventional endoscope was changed to the multibending endoscope, the ESD procedure became safer and more efficient. Another ESD using the multibending endoscope was performed successfully without any adverse events. Conclusions The use of a multibending endoscope for ESD will enable safer and faster treatment of patients. |
